P1: Third-party action is pinned to a mutable tag in publish workflow

docker/setup-buildx-action@v4.1.0 is tag-pinned, not SHA-pinned.

Replace the tag with the release commit SHA plus a version comment.

AI prompt
Check if this security scanner issue is valid. If so, understand the root cause and fix it. If appropriate, update or add tests. Keep the change focused and preserve intended behavior.

<file name=".github/workflows/publish.yaml">
<violation number="1" location=".github/workflows/publish.yaml:72">
<priority>P1</priority>
<title>Third-party action is pinned to a mutable tag in publish workflow</title>
<evidence>The modified Buildx setup step uses `docker/setup-buildx-action@v4.1.0`. GitHub Action tags are mutable; if the action repository or tag is compromised or force-moved, this publish workflow would execute different code without any change in this repository.</evidence>
<recommendation>Pin the action to the full 40-character commit SHA for the intended `v4.1.0` release and keep the version as a comment, for example: `uses: docker/setup-buildx-action@&lt;40-char-sha&gt; # v4.1.0`. Apply the same pinning policy to all actions in the release/publish path.</recommendation>

P1: Second Buildx setup step is also pinned to a mutable tag

Second docker/setup-buildx-action@v4.1.0 is tag-pinned.

Use a full commit SHA instead of the version tag.

<title>Second Buildx setup step is also pinned to a mutable tag</title>
<evidence>A second modified Buildx setup step also uses `docker/setup-buildx-action@v4.1.0`. In a publish workflow, mutable action tags are a supply-chain risk because the workflow may build or publish release artifacts using code fetched from a tag that can change outside this repository's review process.</evidence>
<recommendation>Pin this `docker/setup-buildx-action` invocation to the full 40-character commit SHA for the intended `v4.1.0` release and retain `# v4.1.0` as a comment for reviewability.</recommendation>
